I have a 92 stealth rt, it starts and runs without the MAF plugged in but the idle is not smooth. With the MAF plugged in it will not start. Snap On Solus says there is no communication from the ECU, so I just had my ECU rebuilt and nothing changed. I still get no communication from the rebuilt ECU. If anyone has any ideas I would greatly appreciate hearing them, Thanks

 

You either have an intake leak somewhere, or you have a bad MAF. I have a bunch of MAF's that are tested good. $100
